<p>Disclosed are a method and an apparatus for data mapping on an optical transport network. The method comprises: mapping packet service data or constant bit rate data to an ODUS and mapping the ODUS to an OTUS; distributing the OTUS to multiple electrical channel signals, grouping the multiple electrical channel signals and mapping each of them to a corresponding OChSi. The rate of the ODUS and that of the OTUS are both N times of 100 gigabit per second, the rate of the OChSi is M times of 100 gigabit per second, the timing sequence size of an ODUS and an OTUS branch is 100 gigabit per second, N is a positive integer greater than or equal to 2, i is a positive integer, and M is a positive integer that is greater than or equal to 1 and less than N. Through the present invention, an operator can deploy a beyond-100G optical transport system more flexibly without being restricted by the selection of a fixed rate, improving the utilization efficiency of an optical fiber spectrum and system flexibility and compatibility.</p> |
